Toothpaste factory?

Little A and I went to my work yesterday for a meeting with a boss. We went in a bit early to have lunch with my colleagues. The meeting was about my work tasks when I come back and some other stuff. It was all good enough (the meeting and the lunch) but there is such a lack of energy at my workplace. We're doing really important work, but it feels like stepping into a factory that makes toothpaste or something similarly boring and not very important. There is no enthusiasm. I am happy to come back because in a month or so after I come back I will have earned a higher qualification that means that it will be easier to find other work. I don't think I will stay very long after that.
